Abstract: A refrigerant composition includes R1225ye(E) refrigerant, a second refrigerant that is one of R1234ze(E) refrigerant and R32 refrigerant, and a third refrigerant that is one of R227ea refrigerant, R125 refrigerant, and R1234yf refrigerant. The refrigerant composition has a GWP of at or less than about 2000. A method of making a refrigerant composition includes mixing at least an amount of R1225ye(E) refrigerant, an amount of a second refrigerant, and an amount of a third refrigerant to obtain a refrigerant composition that has a GWP of at or about or less than 2000. A method of retrofitting a refrigerant composition in an HVACR system includes adding an amount of at least one refrigerant to a refrigerant composition to produce a retrofit refrigerant composition that includes R1225ye(E) refrigerant, a second refrigerant, and a third refrigerant.

Abstract: A sealant dispenser system and method for applying sealant to fasteners. The sealant dispenser system comprising a syringe that engages a dispenser head, wherein the dispenser head has a plurality of dispenser feed channels that receive sealant from an intermediate dispenser conduit, which receives sealant from the sealant distribution conduit. The sealant distribution conduit is configured to receive a needle of a syringe which, when filled with sealant, can be engaged to distribute sealant from the syringe barrel through the sealant distribution conduit, through the intermediate dispenser conduit and through the dispenser feed channels and out of the dispenser feed channel orifices. The dispenser feed channels and the dispenser feed channel orifices are positioned proportional distances apart to allow for distribution of sealant around the entire edge of a fastener.

Abstract: A heat transfer cover mitigates temperature changes of an object. A cover body is configured to receive the object. A plurality of heat transfer channels are defined in an interior of the cover body. The channels are arranged to transport a heat transfer fluid in thermal communication with the object. An inlet port is configured to connect the plurality of channels with a source of the heat transfer fluid. An interior surface of the cover body may substantially conform to a shape of an exterior of the object. A plurality of lands may be defined in the interior of the cover body. The lands are arranged to engage the exterior of the object. The heat transfer channels may be defined between adjacent lands. At least a first end of the cover body may define an opening. The at least first end and the object are substantially sealed at the opening.

Abstract: A heat softened glass sheet is conveyed directly from a heating furnace onto an advancing conveyor belt which is supported on a scissor table. The glass sheet is advanced on the belt to a position below an upper press face. The scissor table increases the sag of the belt and the corresponding curved configuration of the supported glass sheet as it lifts the glass sheet into pressing engagement with the upper press face. During pressing, the glass sheet and belt generally conform to the shaping surface of the press face.

Abstract: An adjustable radius conveyor roll for shaping and conveying heat softened glass sheets. Interconnected glass sheet engaging members are rotatably mounted along a flexible shaft of the conveyor roll. The ends of the roll are pivotally connected to pivoting support arms. A roll flexing arrangement includes a collar positioned at the center of the roll and a roll flexing drive to move the center of the roll in a vertical direction to adjust the curved configuration of the conveying roll.

Abstract: An adjustable roll forming arrangement for shaping heat softened glass sheets. Each end of a series of transversely curved, longitudinally spaced forming rolls are mounted on first and second longitudinally extending flexible members. The members may be adjusted so that each roll end is positioned along a desired longitudinal radius of curvature that can be modified by flexing the flexible member.

Abstract: A press bending apparatus includes a shaping station having an upper mold with a shaping surface having a generally concave downward elevational configuration and a lower mold with an apertured shaping surface complementing the shaping surface of the upper mold. A vacuum shuttle transfers heat softened glass sheets from a heating furnace to the shaping station where it deposits the glass sheets on the lower vacuum mold. The glass sheet is shaped between the molds. A rotating arrangement rotates the lower mold and the shaped glass sheet held thereagainst by vacuum from a first position wherein the shaping surface of the lower mold faces upward to a second position wherein the shaping surface of the lower mold faces downward. The shaped glass sheet is then deposited on a tempering ring. A rotating arrangement maintains vacuum in the lower mold as the mold rotates.

Abstract: An adjustable quench for tempering hot glass sheets of varying transverse configurations, having overlapping members that seal a flexible nozzle assembly as it changes configurations. Nozzles extend from the flexible nozzle assembly towards the shaped glass sheet to be cooled such that the quenching surface formed by the head portions of the nozzles generally parallel the major surfaces of the shaped glass sheet. Each individual flexible nozzle assembly is connected to a common drive that can simultaneously flex all the nozzle assemblies.

Abstract: A furnace with the end portions of a heater supporting anchor rod embedded in the rigid sidewall insulation of the furnace. The anchor rods do not deflect under the weight of the heaters and the entire weight of the anchor rods and heaters is supported by the sidewall insulation.

Abstract: Nozzles are arranged in different densities transverse to a path of travel for glass sheets moving through a pass-through quench to facilitate removal of spent tempering medium to both lateral sides of said path of travel.

Abstract: This invention relates to shaping glass sheets by roll forming to either simple or complex curvatures about a single axis of bending or to compound curvatures comprising components of curvature about mutually perpendicular axes of bending by a controlled, repeatable program of roll forming without causing the glass sheets to stop their forward movement during their shaping. The apparatus used to perform this process has a minimum of moving parts, thus minimizing maintenance problems and reducing downtime for maintenance and repair.

Abstract: A conveyor roll for conveying glass sheets and a conveyor comprising a plurality of said conveyor rolls is described. Each conveyor roll comprises a curved shaft conforming to the shape of said glass sheets transverse to their path of movement. A plurality of segments of essentially cylindrical configuration is mounted around said curved shaft. The segments have loosely interfitting tongues and grooves and a cylindrically shaped surface of a material that does not mar glass. When torque is applied to one of the end segments of said conveyor rolls, the glass engaging surfaces rotate in unison to convey the curved glass sheets through a treatment station included in glass sheet treating apparatus. A spring mounted about the shaft in position to apply axial pressure against the outer axial surface of the end segment to insure positive tongue in groove engagement would tend to mar said outer axial surface and to cause the end segment to drag in the absence of the present invention.
